treachregarding the little "internal compiler error" problem, I've ran memtest on my laptop, and it doesn't seem to to be caused by bad ram.09:34
jaegersame here, ran it for more than 6 hours last night, around 13 passes09:35
jaegercouldn't build anything with 4.3.2 i686, 4.3.2 i586, or 4.2.2 i686 from 2.409:35
treachthe really weird thing IMO, is that it builds sometimes, and sometimes not.09:36
treachsame compiler, same code, same settings.09:36
treachit got better with jue's gcc package, but I still get it now and then.09:37
sepeninternal compiler... you should crash your laptop to get the internals09:37
jaegerI couldn't even build sometimes... openntpd, kernel, everything I tried failed almost immediately09:37
treachI assume you tried again with the same settings..?09:38
* treach scratches head.09:39
treachit's insane that it works sometimes, and sometimes not.09:39
treachI've no idea why.09:39
treachsome things, like python would fail consistently at the same place though.09:40
jaegerI tried each several times, with and without CFLAGS set, for each of those 3 compilers09:44
jaegerbroke in the same spot every time09:44
treachmmh, what about glibc? Anyone tried changing that?09:46
treach(since 2.9 is out)09:46
jaegerI haven't yet09:53
tilmanthe changelog from 2.8 to 2.9 looked really boring09:54
tilmanit's unlikely this is a glibc issue imo09:54
treachtilman: I was grasping for straws. :/09:55
sepenbinutils or other toolchain related app?09:55
tilmansepenn?10:00
sepenwhat?10:01
tilmani don't understand the question about binutils10:02
tilman:D10:02
sepenwell gcc, glibc and binutils are toolchain based ports, right?10:02
sepenso I wanted to say that maybe binutils was also a candidate for tests10:02
sepensorry Ill look for changes on it before nothing the next time ;D10:03
tilmanah!10:04
sepenheheh http://ftp.gnu.org/gnu/binutils/README-2.11.110:08

juehello13:38
jue.oO found it possibly ... :-)13:38
treachthat's good news.13:41
juetreach: you can still reproduce the error?13:41
treachno, actually everything has been working today. I guess I could give ff another try.13:42
treachstrange, really. I ran memtest a few times earlier, and it didn't find anything, so I13:43
treach'm cursing the placement of enter.. and currently ruling out bad ram.13:44
tilmanjue: what do you think is the problem?13:44
tilmantreach: :D13:44
jueI've hurried up my i586 build and updated an very old i586 with the core packages, than compiled on that box all instaled opt ports13:44
jueand than I git this: http://66b064e231eb4ba7.paste.se/13:45
jues/git/got/13:45
juestrfuncs.c:961 is a floating point arithmetics, so I suspect that libgmp might be involved13:47
jaegerhrmm13:47
*** Rotwang has quit IRC13:47
tilmanmmh.13:47
juelibgmp tries to optimize much on the build host, even extensions like mmx, sse etc.13:48
juewell, with a generic libgmp the error is gone13:49
jueif someone want/can test it, please install the libgmp from here:13:50
juehttp://jue.ods.org/tmp/13:50
tilmanlet's hilight nipul with that13:51
tilmannipuL: can you try whether libgmp from http://jue.ods.org/tmp/ fixes your ICEs?13:51
tilmanjue: hehe, see the big-ass warning on gmplib.org?13:51
tilman GMP is very often miscompiled!13:51
tilman:D13:51
tilmanmaybe we shuld run 'make check' in the port13:52
jueyes, but I always run a 'make check' with a new version13:52
juethe problem seems to be the host specific optimization13:53
tilmanoh, now i got what you meant13:54
tilmani think :]13:54
jue;-)13:54
jueI've added now a --build=i386-pc-linux-gnu to ./configure13:55
jueafter reading the comprehesive gmp.info13:55
treachhah, just got that error with cups. I'm retrying with the new libgmp.13:57
*** Rotwang has joined #crux-devel13:57
tilmantreach: does it die on cups too at a point where it would try to fiddle with floating point math?13:57
treachprobably, I don't remember the exact error though, but it seemed plausible13:58
treachseems like it works now.14:01
juecool, that's #214:02
tilmanjue: awesome14:02
treachlol, it failed again, but this time it's something else. "No space left on device" :D14:03
treachthanks jue, good catch.14:03
juethanks, but let's wait for another validation14:04
juejaeger: can you test it as well, please ?14:05
juetilman: if you run libgmp's configure you will see something like14:08
jueusing ABI="32"14:08
jue   ....14:08
jue  MPN_PATH=" x86/k7/mmx x86/k7 x86 generic"14:08
tilmanindeed14:09
juemy new port has only 'x86 generic' here14:09
tilmani guess they don't have codepaths for i686 only?14:10
tilmanie plain i686, without mmx fancyness :)14:11
tilmanerm.14:11
tilmanor maybe all i686 compatible cpus have mmx, i don't even know :D14:11
treachmmmh, pentium-m has mmx..14:11
treachyeah14:11
tilmanwe could check the libgmp machine code for SSE instructions14:12
treachiirc even some i586 have mmx, but I could be wrong about that14:12
tilmanor SSE2, or whatever14:12
tilmantreach: i think pentium-pro was the first cpu to feature mmx14:12
tilmani have a feeling rehabdoll will correct me in a few seconds14:13
juesure, we can try i686 if it really was the problem14:14
juefor now I used i386, because they wrote that it is the best generic setup14:15
jueand it has to run on my very old K6 ;-)14:16
tilmanthere was a 'pentium mmx' ftr ;D14:16
treachyeah.14:16
treachI think the slowest was 133 mmx or something, but that was pretty uncommon.14:16
treach166Mhz was pretty common as mmx14:16
treach(jeeez that was AGES ago) =)14:17
jueindeed14:17
jueusing --build=i686-pc-linux-gnu leads to MPN_PATH=" x86/p6 x86 generic"14:42
jueguess that's what we want14:43
jaegerjue: pretty busy, didn't follow the thread of conversation. you want me to test the libgmp from the ods.org link above?14:43
jaegerI can do it later tonight when I'm at home, don't have the p3 laptop here14:43
tilmanjue: that looks good to me :)14:43
juejaeger: yes14:44
juehope it works ...14:44
jaegerI'll try it when I get home and let you know14:48
